How to georeference an image in erdas imagine 2014

From the ERDAS IMAGINE 2011 main menu bar click on the Multispectral tab and change the sensor to WorldView-2 in the Bands group. Note: Multispectral Imagery from DigitalGlobe resides in a subdirectory with a _MUL in the folder name (e.g _01_P001_MUL) Fig.7. From the ERDAS IMAGINE 2011 main menu bar click on File > Open > Raster Layers and navigate to the folder that contains your WorldView-2 image. For an in-depth look at the benefits of the Eight Spectral Bands of WorldView-2 please visit 5Д¦ 1. In IMAGINE 2011, ERDAS has added additional band combinations designed specifically for WorldView-2. This allows for more of the visible spectrum to be absorbed by the sensor ultimately providing more information within the pixels of the image. WorldView-2 not only images with those bands mentioned but also employs the Coastal Blue Band, Yellow Band, Red-Edge Band and Near- Infrared 2 Band. Up until the launch of WorldView-2 most high resolution satellites imaged with four (4) multispectral bands (Blue, Green, Red and Near-Infrared) or less. On the main menu select File > Open > Raster Layer and navigate to the folder with your new Orthorectified Image Switching Band Combinations with WorldView-2 WorldView-2 is the first sensor of its kind to offer 8 multispectral imaging bands. Once the orthorectification process is complete, dismiss the process window by clicking Dismiss and open the new Ortho Image in the viewer. Note: This feature works for both NITF and TIFF tiled files, and the.rpb file must reside in the same folder as the imagery tiles for proper georeferencing. Users can type *.TIL in the file chooser to expose this option. Additionally, this support can be used for direct-read scenarios, so the assembled tiles can be used directly in workflows without first processing them into a new file. The georeferencing information (RPC) is still preserved (see DigitalGlobe RPC in ERDAS IMAGINE documentation for RPC explanation). The ERDAS IMAGINE importer now allows you to select a.til file and import all the tiles into a single file. To use these files in georeferencing workflows, they must be assembled back into a single original image. An ancillary.til text file provides a list of these tiles and their relationships. To better handle these large files in 3 rd party software, DigitalGlobe s customers have the option to tile the imagery. Often times image files can be extremely large in file size.

DigitalGlobe often delivers images cut into smaller tiles that do not overlap. 1 WORLDVIEW-2 Imagery Basics and ERDAS IMAGINE Import DigitalGlobe tiled data (.TIL) with ERDAS IMAGINE ERDAS has added support in IMAGINE 2011 for the DigitalGlobe.TIL format.
